OmniBase is a multi-user, fully object-oriented database for Smalltalk. It provides a complete solution for multi-user access to shared objects, persistency, transactions with two-phase commit, pessimistic concurrency control and object-level locking.

Changes from 2.1 rc 47: TwoByteString support, Float fixes, GC does not raise progress dialog (unsuitable for headless apps).

Installation

Install OmniBase into your image by loading parcel OmniBase.pcl. The parcel has been saved with VW7.7, but it should work with other VW7 releases of VisualWorks.

Documentation

OmniBase tutorial and API reference can be found on the internet at http://wiki.gorisek.com http://www.gorisek.com VisualWorks distribution also includes a PersonnelFiles.pcl parcel which demonstrates one of possible strategies for making business objects persistent and indexable using OmniBase. Note, that OmniBase does not prescribe you a persistency model for business objects. OmniBase only provides a way to persist Smalltalk objects in a multi-user environment. As in Smalltalk itself, the implementation of the object model is up to the application developer using OmniBase.
